Editor’s note: The Ninth Circuit hears oral arguments in Amazon v. Perplexity on Thursday, June 11, 2026 — the first federal appellate test of whether AI agents acting under user authorization count as authorized visitors to logged-in commercial websites. The ruling will reshape what every agent in this directory is allowed to do.

Not a chatbot. Not an LLM with a wrapper. An AI agent is an autonomous system that takes a goal, plans the steps to achieve it, executes those steps using tools, observes the outcome, and adjusts. The defining capabilities are planning, tool use, memory, and execution loops.
Agents do work. Tools do not.
EPR draws the line strictly. Chat interfaces with one-shot tool calls are tools — they go in the AI Tools Directory. Multi-step autonomous task completion with real tool use is the agent bar.
Categories
Fourteen categories. Each becomes a browseable page with all EPR-ranked agents in that vertical.
Editorial judgment — is this an agent or a glorified workflow?
Rankings are editorial. Vendors cannot pay for placement.
